ln the above views the corresponding parts are represented by the same reference nut5 merals.

Attention is first directed more articularly to Figs. l and 2 inwhich a chain. conveyer 1 has fastened thereon the carriers 2 by means of the countersunk screws 3 on the eo specially formed links 4f. The carriers 2 are suitably designed to receive the articles to which the labels are to be applied. llhe particular machine of the drawingsshows U- shaped carriers which are suitable for han- 85 dling shoe laces. 'lhe chain conveyer 1 is shown meshing with a sprocket wheel 5, it being understood that a corresponding sprocket wheel meshes with the conveyer chain at the left oit the drawings. Them) sprocket wheel 5 is locked on the shaft tl by means of the'lock pin 7 d `iven through the sprocket wheel hub and sh ft, as will be understood. The shaft 6 runs in suitable anti-friction bearings in the side trames 8 95 and 9 and is driven in a manner to be hereinafter explained. 'llhe upper portion of the chain conveyer 1 rides upon a rail l() which is centrally supported between the side frames 8 and 9 by means of the supports 11 100' folding plate, the folding finger, and the moistening pad, respectively.

ifs

Cooperating with the cam 14 is the roller 17 (Figs. 1 and 6) on the shoulder pin 18 fastened on t-he lever 19 which is rigidly secured to the shaft 20 protruding through, and free to rotate in suitable bearings in the sideframes 8 and 9. Upon the outer ends of the2 shaft 20 (Fig. 2) `are secured the levers 19a the upper ends of which are slidably attached to the arms 21 of the sliding folding plate 22 by means of the shoulder pin 23 securely fastened to the arms 21, and which rides in an elongated slot in each lever 19, as shown in dotted lines in Figs. 1 and 6.

r1Fhe sliding plate 22 slides upon the top of the side frames 8 and 9 and in a cut-out portion of the plate 24 which is fastened to the side frames 8 and9 bymeans of screws 25 (Fig. 7 llhe arms 21 of thesliding plate 22 extend through the slots 26 cut in the plate 24 (Figs. 5 and 7 to allow the free movement of the plate forward and bachward. Screwed into the sliding plate 22 and passing through'the slot 27 (Figs. 6 and 7) in the plate 24 is the screw 28, about which is hooked one end of the coil spring 29,the other end of `which is hooked about the anchor screw. 30 screwed into the plate 24. 'Fhe front end of the sliding plate 22 (Fig. 7) is provided with the protruding portion or finger 22a, and with the shoulder 22h, the purpose of which will be described hereafter.

Riding in contact with the face of the cam 15 (Figs. 1, 3 and 4) is the roller 31 on the shoulder pin 32 fastened in the gear sector 33 which rotates on the shoulder portion of the pin 34 (Figs. 3 and 4) mounted in side frame 8. Meshing with the teeth of the gear sector 33 is the pinion 35 rigidly secured on the shaft 36 which is free to rotate in suitable bearings in the side frames 8 and 9, as shown in Figs.l 2 and 4. Around the shaft 36 is the coil spring 37, one end of which is fastened into the pinion 35, with its other end anchored in the rail 10. Arms 38 are also rigidly secured to the shaft 36l (Figs. 1, 8 to 15), and these arms have pivotally attached thereto by means of the pivot screws 39 the folding lingers 40 having an extended leg portion 49a, the purpose of which will be described hereafter. 'lthe small' coil springs 41 (see particularly Fig. 4) are heldin position by the pivot screws 39, and each has one end anchored by the 'libanesa corresponding arm 38 and the other end bears against the corresponding folding linger 40. Screwed into the side frames 8 and 9 (Figs. 2 and 4) are the trip pins 42 which cooperate with the folding lingers as will be described hereafter.

Engaging the face of the cam 16 (Figs. 2 and 5) is the roller 42 rotatably mounted on the pin 43 secured in one end of the lever 44 which is freetc rotate on the bushing 45 located on the outer yend of the pin 34. Secured inthe upper end of the lever 44 is the pin 46, upon the shoulder portion of which is the roller 47 (Figs. 2 and 5) free to roll inl the slot 473 in the end of the lever 48 fastened on the shaft 49 (Fig. 2). lThe lever 48 is provided with a collar 48L which is secured to the shaft 49, the latter being free to rotate within the long bearing 24n carried by the plate 24. @n the other end of shaft 49 is fastened the lever 50 which has integral therewith the moistening pad block 51, which carries the moistening pad 52 (Figs. 2 and Screwed into the block 51 (Figs. 1 and 5) is the nipple 53 over which is slipped one end of the flexible tubing 54, the other end of which is slipped over the outlet of the pet-Coeli 55 screwed into the face of the reservoir 56 carried by a standard Y57, the latter being heldin position bymeans of the 'screws 58 through plate 24. .d coil spring 59 has one end hooked in a hole in the lever 50 and the other end is anchored in a hole in the standard 57.

Fastened to 'the tops of the side frames 8 and 9 (Figs. 1, 2, 4, 7) are the plates 61, there being suiiicient clearance between 'the ends of these plates 61 to allow for free passage of the carriers 2. also secured to the side frames 8 andi) is the plate 62 which extends across the entire width of the machine and is curved on a radius (not shown) to conform 'with that of the conveyer chain and to just clear the tl-shaped carriers when they are moved around by the sprocket wheel 5. the lower end of andso fashioned as to extend above the plate 62 (Fig. 1) are the ejector fingers 63 which are securely held in position on the stationary shaft 64 byy means of the blocks 65 and screws 66. rlthe purpose of these plates and operation of the ejector hlngers will be later described.

Having now identified the various parts of my improved machine, l will now proceed with a description of its operation.

rlhe labels or wrappers L and the articles A aboutwhich the labels or wrappers are to be fastened, are deposited into the U- shaped carriers (Figs. 8 to 15) either by means of suitable mechanism for that purpose or by the hand. of an operator. This operation is carried on in proper timing with the mechanism for driving the machine. rlthe driving mechanism employed may be the well lrnown Geneva movement to give l to the sprocket wheel shaft 6 an intermittent `or step-by-step movement. The cam shaft 13 is rotated continuously and the cams 14, 15 and 16 are so positioned that proper timing relation may be had between the various operating parts and the stop and start motion of the conveyer chain 1. Each forward movement of the conveyer chain 1 brings the following U-shaped carrier up to the leading edge ofthe plate 24 (Fig. 1) where it is given a period of rest long enough to allow for moistening the gummed portion of the label. andfolding its ends down. This folding operation I will lnow describe, referring particularly to Figs. 8 to 15 inclusive, which illustrate the relative positions of the parts during one complete revolution of the cam shaft 13. p

Figs. 8 and 9 show the carrier 2 just after it has come to rest, the arm 38 having been swung upward. This upward swing of the arm 38 begins shortly before the carrier comes to rest and receives its motion by means of the roller 31 taking the rise of the cam 15 (Figs. 1 and 3). l:The cam .15'is revolved in a clockwise direction and on raising the roller 31 upward revolves the gear sector 33 in a counter clockwise direction causing the pinion 35 to revolve in a clockwise direction, thus swinging the varms 38 upward. During theupward swing of arms 38 the extended legs 40a of the folding fingers 40 come in contact with the trip pins 12 as shown in Fig. 8. This causes the folding fingers toto swing inward toward the center of the machine (Fig. 4). This inward swing of the folding fingers 40 is so timed as to allow them to clear the chain conveyer 1 and when the swinging -movement has been completed the ends of the fingers 10 have passed above the carrier 2 causing one end of the label L to be folded down upon the article A (Figs. 3, 8 andr9). At this fpoint the roller 3-1 is riding on the dwell o the cam 15 (Fig. 3) causing the fingers l0 to remain in this position for y reasons more fully described hereinafter.

` At this point the roller ft2 which has been running 'on the'dwell of the cam 16 causing the nioistening pad to be held upwards, comes in contact with the fall of the cam 16v (Fig. 5) thus allowing the coil spring 59 which is under tension to pull the arm 50 sharply downward and inward, bringing the moistening pad 52 in contact with-the gumrned portion of the label L as shown in Fig. '10. The moistening padV block then immediately starts to swing backward and upward again (Fig. 11) due to the roller,

4.2 taking the rise of the cam. 16, causing the lever lll to be oscillatedv -in a counter clockwise direction and forcing the arm 48 to be swungv backward and upward in a clockwise direction, thus partially rotating the shaft 49 and swinging the arm 50.

- sure the holdin During the first part of this backward swing ofthe moistening pad 52 the slidingfolding plate 22 is moved forward at the same rateY 22" receives its motion from the roller 17y riding the rise of the cam 161, thereby oscillating the levers 19 and 19a on the shaft 20 for that purpose (Fig. 6). action of the label against the moistening pad is caused by the protruding portion or linger 22a of the sliding plate 22 which,

passes between the folding fingers 40 (Fig. 4) and thus holds the foldedend down before theA folding fingers 40 are swung out and downward to their normal position (Figs. 12 and 13). The folding fingers are'` swung outward by means of the springs 4:1 actuating upon the fingers, as the extended This wiping leg portions 10al thereof contattwith the trip pins l2 during the movement of the.

arms 38 from the position of Fig. 12 to Fig. 13. This movement of the arms 38 is effected by the coil spring v37 turning the shaft 36. The folding fingers start to recede from the label before the sliding plate 22 has finished its forward movement, allowing a clearance for th`e shoulder 22b of the sliding plate 22 which insures they folding down smoothly across its yentire width ofI this end of the label which had not been foldedv up to vthis point (Fig. 13). At this point the conveyer chain-'1 starts to move, and at the same time the sliding folding plate 22 recedes with it (Fig. 1t) until it reaches the end of its movement, but the conveyer chain continues on until the next carrier 2 is in the position as shown in Fig.`- means of 15, Where it is brought to rest b the Geneva movement, and the fpdlding and moistening operations are.` ready to start over again. .The sliding folding plate 22 is brought back to its normal position by means ofthe coil spring 29, the roller 17 f riding down the fall of the ,cam 1li.

With each successive folding and moistening operation the carriers 2 bring the labelled articles or packages back under the sliding plate 22, and from there they ride under the plate 62. These plates hold the gummed ends of the labels down firmly, allowing enough time for the two ends of the label to firmly adhere. As the packages or (Fig. 1) they are pushed out of the carriers (which are now 11p-side down) by the stationary ejector fingers 63, which will be 'clearly understood from Fig. 1.

lem

particles reach the lower end of the plate 62 As a modihcation ot my invention, Figs.

16,17 and 18 show the use ol a single folding rails, thereby allowing the use of a single` folding arm rising npward between` them. The folding arm 38a is cutl or slotted away at its lower end to allow the pinion 35 to be placed in position (Fig. 18) and the'shoul- .38 back to its normal mechanism tor causin dered portieri of the pin 34 is lengthened and likewise the hub ot the gear sector 33. 'lhe method oi bringing the folding arm osition is the same as that already descri ed, excepting that one end ol the coil spring 37 is fastened in the folding arm 38m instead ofthe vhub oil 'the gear 35. 'lhe other end is anchored in the side traine 9 instead ol the rail 10. 'lhe timing and operation of this modified tolding arxn are the saine as already described.A
